Hi,
Work:
Equation;
[tex] |x| = - |x| [/tex]
The statement is true only if both sides are equal to 0.
[tex] \binom{ |x| = 0}{ - |x| = 0 } [/tex]
Calculate for both x.
[tex] \binom{x = 0}{x = 0} [/tex]
Find intersection.
[tex]x = 0 \: \: \: \: \: \: \: result[/tex]
The answer is sometimes. The statement is true if x is 0, and everything else is not possible.
Hope this helps.
